METHOD AND APPARATUS FOR ORNENTING MINERAL-SURFACE!) ROOFING.

Application filed December 3, 1920. Serial No. 427,938.

To all w homit may concern:

Be it known that I, CARL J. PATER, a citizen of the United States, and aresident of Wyoming, in the county of Hamilton, State of Ohio,'whosepost-ofliceaddress is 231 Grove Avenue, l/Vyoming, Ohio, have inventednew and useful Improvements in Methods and Apparatus for OrnamentingMineral-Surfaced Roofing, of which the following is a specification.

My invention relates to method and apparatus for ornamenting preparedroofing, more particularly the ornamenting of mineral surfaced preparedroofing on which the ornamentations are made by compressing the mineralsurfacing particles down into and covering them with the coating whichbefore the ornamentation treatment underlies and holds the mineralsurfacing particles in place. Roofings of this type are usually made byusing a foundation of one or more plies, such as felt, paper, etc.,saturated or impre nated with a suitable watefproof material such asasphalt or other bituminous substances and then coating with a suitablewaterproofing compound, such as an asphalt compound or other bituminouscompound to cover the foundation. Upon this coating is then appliedmineral particles of either crushed slate, stone, pebbles, sand, mica orother particles of suitable fire-resisting .materials.

Roofings of this type are manufactured and sold without anyornamentations. When these roofings are used'where a more decorativesurface is desired and they are sub jected to an embossing operationwherein a face of the mineral particles pressing the particlesalongpredetermined lines down into and covering them with the bituminouscoating which has been softened by the heated design roller. In practiceit has been found that this ornamenting of the roofing by embossingresults in a readjustment or reformation of the roofing alongpredetermined'lines and is facilitated by heating the roofing prior tothe embossing operation. This heating of the roofing prior to theembossing operation however tends to cause it to adhere to thefoundation on which it rests when the embossing operation is performed;it also stretches the roofing along the edges, and has other objectionswhich I have found can be overcome and the speed of production greatlyincreased by subjecting the under side of the roofing to a film .orcoating of liquid or other non-adhesive material preferably cool or coldwater.

My improvement prevents the stretching of the roofing along itsedges-which gives a fluted'efi'ect and prevents the roofing from lyingflat on the roof when in place.

In the drawings in which like letters refer to like parts, Fig, 1 is adiagrammatic view of the apparatus of my improved apparatus. Fig. 2 is across section of Fig. 1 taken on the lines 2, 2 looking toward theright. A is the embossing roll having any suitable raised design on it.This roll is heated preferably by a flame A A which may be located onthe inside or-outside of the roll or on both, fuel for which is suppliedby pipes A A An suitable heating medium may be used. is the support-.ing or foundation roll upon which the roofing rests whilebeing embossed.The embossing roll A and the supporting roll B are driven in any desiredwary, but as shown A is provided with a gear meshing with a similar earQ, on the shaft of roll B. The gear is fixed to the shaft of roll A asis also the pulley R driven by belt or otherwise. If desired the roll Ais mounted so as to'regulate the pressure-on the roofing on either orboth ends of the roll. G

is a continuousbelt or carrier adapted to it. F is an idler roll tofacilitate the rolling up of the roofing after the operation is applied.G is a steam coil or other suitable means for heating "the roofingbefore it reaches the embossing roller. This heating means may belocated below the roofin I as shown, or above it or both above an below.I is a roll of mineral surfaced roofing which is being ornamented by myim proved apparatus and method. J is a tank or receptacle which containsa suitable liquid, or other material, preferably cool- .or cold water sothat as the foundation roll B rotates in the direction of the arrowiting operation for the purpose of cooling immerses itself in the waterand receives a very light film which it carries up and imparts in partor in whole to the under surface of the roofing simultaneously with theembossing roll treating the opposite surface of the roofing to theornamenting process. K is a pipe or other inlet from any suitable sourceof supply, for the receptacle J, having located near the receptacle avalve to control the amount of liquid or other film coating materialthat enters the receptacle. L is an outlet from the recep-- tacle Jhaving likewise a suitable valve in it to control the amount of filmcoatingmaterial'that is passing out of the receptacle other than theamount which is carried out by the rotation of the foundation roll B.

In practice I prefer to use cool or cold water as the film coatingmaterial although oil or any other suitable material that will notdestroy or effect the under side of the roofing is satisfactory for thispurpose. In the use of cool or cold water or other suitable liquid thefilm, on the foundation roll B, acts to cool the under side of theroofing and prevents its adherence to the foundation roll, while theembossing operation is being performed. In using water or a similarliquid to keep it at an even temperature,

or to constantly have a supply of cleanliquid, if desired a continuousflow into and out of the receptacle J may be maintained. It is desirablein the orna-menting of the mineralsurfaced roofing that the cooling ofthe under side of the roofin extend not beyond the saturated felt; inother words that the cooling prior to or at the time the embossingoperation is performed in no way chills or cools the coating material asthedecorating or ornamenting of the roofing depends upon thereadjustment of the plastic coating material in predetermined areas topermit and facilitate the mineral surfacing being pressed into andcompletely covered by t e coating. f

My improved. method ,of manufacture using the apparatus shown is to takea complete roll of marketable mineral surfaced roofing, subject it toheating process'andf then pass it between two rolls, one of which has adesign on itthe design lines being heated and the under roll having afilm of water on it which contacts with the under surface of theroofing, simultaneously with the embossing roll contacting withthe uppersurface of the roofing, thereby preven ng adherence of the roofing tothe foundation roll, cooling the roofing on its under surface whichpermits increase of speed of the operation of the rolls thusfacilitating the speed of ornamenting. The liquid film not only acts toprevent the adherence of the roofing to the foundation roller B, butalso tendsto cool the under surface of the roofing without affecting thetemperature of the coating material which has been softened by thepreheating operation. After the em bossing operation the roofing is thenpassed around suitable cooling rolls which act to cool the same from theupper'surface.

In practice I have found that my improved apparatus and method greatlyfacilita-te the speed of operation of the ornamenting of the roofingwhile overcoming many of the objections which have heretofore existed inthe manufacture of mineral surfaced ornamental roofing.

What I claim '1. In apparatus for ornamenting roofing of the characterdescribed, a-heated embossing element for forcing the mineral surfacinginto the roofingco'ating, a supporting element for the roofing arrangedadja-V cent to said embossing element, and means for imparting a liquidfilm to said supporting element. 7

2. In apparatus for brnamenting roof ing of the character described, aheated eral surfacing into the roofing coating, a rotating supportingelement arranged adjacent to said embossing element,'a liquid,

containing receptacle in which the said rotating supporting elementrotates.

3. In apparatus for ornamenting roof-- ing of the character described, aheated embossing element for forcing the mineral surfacing into theroofing coating, a
